Furnace grate



March '15, 1927. J T. WILLARD FURNACE GRATE Filed March 16, 1923 2Sheets-Sheet 1 ing portion being disposed between a pair of dependinglugs 20 which are formed integral with the under side of the annularportion 2 of the grate-rest 1, said projecting portion 19 and the pairof lugs 20 providing means for limiting the amount of oscillatingmovement to be given to the shak ng splder 10.

'Another of the closure portions 13 1s provided with a projection 21 forthe engagement of'the socket portion of a shaking handle which is tobeengaged overthe pro ection 21.

In the operation of this improved grate when ashes accumulate thereon,the shaking handle is engaged over the projection 21 of the shakingspider 10 and when the bandle is moved in a right hand direction thespiderlO will be horizontally turned upon the grate hanger 6 and as sa dspider 1s turnedeach closure portion. 13 will be moved out'or away'fromits closing position with respect to each respective space 18 therebyprovidingv an opening between eachad acent pair of grating portions 301the grate-rest 1. Owing to the pushing or wiping fingers 17 being alsocarried by the shaking spider 10, when the spider is moved and theclosure portions 13 therewith, the push ng or wiping fingers 17 willalso be moved and nuts much as the fingers 17 are each respectivelyengaged-above a respective grating'portion ,3 of the grate-rest 1,'theaccumulated ashes upon each grating portion 3 W111 be pushed off into anadjacent respective spaclng or discharge openinglS. V

The turning movement of the shaking spider 10 is stopped by engagementof the projection 19 with one of the limiting lugs 20 and in'suchstopped position the fingers 17 will be adjacent the opposite edge of iI their respective grating portions 8. The

shaking spider 10 is moved in the opposite direction by rearwardmanipulation of the shaking handle in which the closure portions 13 willbe returned to their neutral positions between respectiveadjacent pairsof grating portions 3. I a

In the event that clinkers and the like becomelodged withinthe openingsor spacings 18"when the closure portions 13 are dis engaged. from saidopenings, return movement ofthe shaking spider 10 will cause the closingportion 13 thereof which'is adjacent the lodged clinker to wedge theclinker against an edge of the adjacent grating por tion 3, such wedgingmovement against the clinker breaking it. i

The cone shaped central portion 11 of the shaking spider 10 during theshaking movement will divert the downwardly moving ashes outwardlytowards the openings 18 and the grating portions. 3. l I V 7 From aninspection of Fig.4,it is to be n ted that'th pushing fingers 17 areelebeneath said vated a slight distance above the grating portions 3 sothat they will not bear against said portions and cause friction.

What I claim is 1. A. grate provided with a grate-rest, said grate-resthaving a pluralit of discharging openings, closure means ormed on 7 saidgrate for each of said openings located on aplane below, said openings,and a plus.

rality of pushing elements borne by said grate located on a plane abovesaid openings movable with said closure means for co -op eration withsaid openings.

2. A grate having a grate-rest, said graterest having a plurality ofdischarging open ings, closure means formed on said grate for each ofsaid openings located on a plane be-- low said openings, supportingmeans for said grate, means depended from sald grate-rest tor upholdingsaid supporting means, and a plurality of pushing elements carried bysaid grate located on a plane above said openings of said grate-rest,said pushing elements being movable with said closure-means forcooperation with said openings.

3. A grate provided with a grate-rest, said grate-rest having aplurality of discharge openings, a cone shaped shaking member. arrangedcentrally of said grate-rest, means for supporting said member from saidgraterest, means borne by said member and ar-- ranged on a plane beneathsaid grate-rest for closing said openings of said grate-rest, and aplurality of pushing fingersborne by said member each being so-operablewith a respective opening and arranged above said openings. t j

4. A grate provided with a grate-rest, said grate-rest having aplurality of inwardly disposed discharging spaces, a shaking memberarranged centrally of said grate-rest andthe spaces thereof, hook-shapedportions depended from said grate-rest, a hanger removably mounted onsaid hook-shaped portions for supporting said member, and means borne bysaid member arranged beneath said grate-rest for closing the spaces ofsaid grate-rest. V

5. A grate provided with a grate-rest, said grate-rest having aplurality of discharge openings, a shaking member arranged centrally ofsaid grate-rest and the openings thereof, hook-shaped portions dependedfrom said grate-rest, a hanger removably" supported from saidhook-shaped portions.v

having an upwardly extending hub, said member having a centrallydepended projection for engaging within the bore of the hub Y of saidhanger, and a plurality of closing portions borne by said -memberarranged. grate-rest each being ice-operas ble with a respectivedischarge opening of said grate-rest;

6. A grate'provided with'a grate-rest, said grate-rest having aplurality of discharge openings, ashaking member arranged centrally ofsaid grate-rest and the openings thereof a hanger removably supportedfrom said grate-rest having an upwardly extend ing hub, said memberhaving a centrally depended projection for engaging within the bore ofthe hub of said hanger, a plurality of closing portions borne by saidmember arranged beneath said grate-rest each being co-operable With arespective discharge openin of said grate-rest, and a plurality of pusling fingers borne by said member each being co-operable with arespective discharge opening of said grate-rest and arranged above saidopening.

7. A grate for a furnace or the like comprising a grate-rest, saidgrate-rest being in the form of a support ng ring and havlng a pluralityof radially disposed spaces formed on its inner periphery, a shakingmember supported from said ring having a plurality of radially disposed"closure portions ex; tended outwardly therefrom, said closure portionsbeing depended so as to underengage said ring and respective dischargingspaces thereof, and a pluralityof pushing fingers borne by said memberon a plane above said ring, each being arranged forwardly of arespective closure portion. 1
